Abstract

The invention relates to an extractor (1) comprising a rod (2) having a handle (4) at one end and, at the other end, an attachment area (3A) that engages with the conical spacer in order to extract same from a concrete wall. The extractor (1) also comprises a movable element (5) that can be moved by the user along the rod (2) between a retracted position into which the movable element (5) is moved in order to extract the conical spacer, and an advanced position into which the movable element (5) is moved in order to push the conical spacer, thereby releasing same from the attachment area. The attachment area is first secured to the conical spacer and subsequently the movable element (5) is moved into the retracted position, thereby extracting the corresponding conical spacer. Finally, the movable element (5) is returned to the advanced position, thereby releasing the conical spacer from the attachment area.
